PolarArea: point labels overlap on certain circumstances #11946

Expected behavior

The point labels should not overlap, when using the option display: 'auto'. This option was enabled for the polar area with #11055.

Current behavior

The labels overlap sometimes, instead of not displaying them. This depends somehow on the size of the labels (length) and/or the size of the chart.

Depending on the size, the labels may overlap more or less. The detection of overlapping labels seems to work only partially. See the second chart in the sample, with more space, no label overlap, despite not showing all of the 100 labels.
